unfold_track

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must fully disclose behavioral traits, but it only says 'Unfold (expand) a group track.' It does not mention side effects, reversibility, whether any state is mutated, or what happens if the track is not a group. This is insufficient for a mutating tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise and front-loaded, with a single purpose statement followed by a parameter explanation. Every sentence earns its place with no redundancy or fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with one parameter and no output schema, the description explains the action and parameter adequately. However, it lacks context about when to use it, any side effects, or how it relates to fold_track, leaving gaps for an agent navigating similar tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description provides a brief semantic for track_index ('The index of the group track'), adding meaning beyond the schema's bare type. However, it lacks details such as zero-based indexing or how to identify the index, so it only partially compensates for the 0% schema description coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Unfold') and resource ('group track'), making the core purpose clear. It does not explicitly reference sibling tools like fold_track, so it misses the extra differentiation that would merit a 5, but the meaning is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when to use this tool versus alternatives like fold_track or ungroup_tracks. There is no mention of prerequisites (e.g., track must be a group track) or context, leaving the agent to infer usage from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
